Abstract

CIRCUITO DE PROTECCION AUTOMATICA EN CASO DE FALLO QUE SE UTILIZA CON UN MOTOR DE CORRIENTE CONTINUA (10) QUE FUNCIONA DE FORMA INTERMITENTE, QUE SE CONECTA POR MEDIO DE UN CIRCUITO DE RUPTURA (14) A UNA FUENTE DE ALIMENTACION (12), A LA VEZ QUE UN CIRCUITO DE CONTROL (21) SUMINISTRA PULSOS CONTROLADOS AL MOTOR DE FORMA INTERMITENTE. EL CIRCUITO DE PROTECCION INCLUYE UN CONDENSADOR (38) QUE SE CARGA CUANDO LOS CITADOS PULSOS SE APLICAN AL MOTOR Y QUE SE DESCARGA CUANDO NO SE APLICAN. SE GENERA UN VOLTAJE DE REFERENCIA ( $G) QUE SE COMPARA CON EL VOLTAJE ALMACENADO EN DICHO CONDENSADOR Y CUANDO ESTE SUPERA AL DE REFERENCIA, SE PROVOCA LA RUPTURA DEL CIRCUITO PARA INTERRUMPIR LA ALIMENTACION AL MOTOR.
